Which Type Of CPU Cooler Contains Heat Pipes?

CPUs are liable to overheat quickly due to the simultaneous execution of thousands of tasks. As a result, it requires prompt and sufficient cooling. Now, a CPU can cool in a variety of methods. Fan cooling is the most often used method. Even yet, liquid cooling is still used in particularcomputers.

On the other hand, heat pipe cooling is a viable alternative nowadays, so the obvious question is: What kind of CPU coolers are equipped with heat pipes?

This article will look at the CPU coolers containing the heat pipes and the best choice for your CPU. Let’s get started!

What Are CPU Cooler Heat Pipes?

A Heat pipe is a vacuum-sealed copper tube that quickly transfers heat away from its point of origin. Using capillary action, a heat pipe with high thermal conductivity may quickly transport and disperse heat to a more convenient place. Heat pipes are the best cooling solution for high-power processors due to the restricted space and power available in computers and electronic devices.

Which Type Of CPU Cooler Contains Heat Pipes?

Heat pipes aren’t a new concept, as you would expect. Theyhave already been implemented in a variety of computer and automated systems. They are still employed in current CPU systems to take heat from GPUs and deposit it in heat sinks, which may dissipate to the outside environment.

Types of Heat Pipes

The following types of heat pipes are available for electronic devices. Let’s discuss these types one by one in detail.

1. Loop Heat Pipes

Like a loop thermosyphon, a loop heat pipe operates against gravity, with the evaporator above the condenser. Its functioning is dependent on the working fluid’s capacity to generate a sufficient amount of vapour pressure.Moreover, when heated to force the liquid condensate back to the device’s evaporator portion.

2. Rotating Heat Pipes

To transport the liquid back to the evaporator, rotating heat pipes utilize rotational force to move the fluid. Rotating heat pipes are often used to remove heat from rotating equipment, such as rotary joints used in radio frequency transmissions.

3. Oscillating Heat Pipes

As they travel to colder regions, they create pulsating pockets of liquid and vapors. That is how they got their name as Oscillating or pulsating heat pipes.

Oscillating heat pipes provide many advantages over conventional heat pipes. It can operate over greater distances and superior performance while operating against gravity.

4. Standard Heat Pipes & Vapor Chambers

Standard heat pipes and vapors chambers (constant conductance devices) have large temperature swings at the evaporator. They are superior to variable heat pipes.

In the field of electronic cooling, constant conductance heat pipes (standard or CCHP) and vapors chambers are by far the most common types of heat pipes utilized.

5. Variable Conductance Heat Pipes (VCHP)

Variable conductance heat pipes (VCHP), as opposed to conventional heat, reduce temperature fluctuations at the evaporator, often at the bottom end of the working ambient temperature.

6. Thermosyphon & Loop Thermosyphon

Although they may contain a grooved ‘wick’ to enhance the interior wall’s surface area and enable liquid condensate to return to the evaporator more readily, thermosyphons are often just wickless heat pipes. As a result, gravity canutilize to return the liquid to the boiler. It allows thermosyphons to transfer heat across greater distances.

Which one is better?

In the field of electronic cooling, constant conductance heat pipes (standard or CCHP) and vapors chambers are by far the most common types of heat pipes utilized.

How Long Do Heat Pipes Last?

This is the question that came to the mind of every buyer who want to purchase heat pipes for their CPU cooler.

Heat pipes have greater failure rates at the beginning of their lives, owing to early infant mortality, and at the end of their lives, due to wear-out. Typically, after the initial few hours of operation, a heat pipe will last thousands of hours before failing.

Heat pipes intend to run without maintenance for extended periods. The service life of a well-planned, carefully constructed, and properly applied heat pipe will be more than 15 years.

Can Heat Pipes Freeze?

Yes, Heat Pipes will often freeze when the temperature outside the building where the pipes locate is 20 degrees Fahrenheit. The freezing point of all heat pipe working fluids, including water, remains at its usual level.

Heat pipes will not function until the fluid temperature rises above the fluid’s freezing point. Heat pipes that are correctly constructed, on the other hand, will not be harmed by freezing or thawing of the working fluid.

Moreover, it is necessary to have confidence in the ability of heat pipes to withstand the freeze-thaw cycles that occur in CPU coolers. Furthermore, the tube itself must be waterproof to bursting.Moreover, the boundary layer composition of the sintering copper wick must withstand the effects of deformation.

Do Heat Pipes Dry Out?

Heat pipes may run for short periods at temperatures greater than their capillary limits while maintaining their steady-state without experiencing dry out.

However, as soon as you open the heat pipe, the liquid begins to evaporate. However, the quantity of liquid in heat pipes evaporates is so tiny that you’d never even notice it.

Does More Heat Pipes Mean Better Cooling?

The amount of heat transferred by a heat pipe depends on:

  • The heat pipe’s effective surface area.
  • Material of heat pipe and
  • Cooling fans

More heat pipes indeed disperse more heat than a smaller number of heat pipes. However, this is entirely dependent on the factors listed above. As a general rule, as the number of heat pipes increases, the result is better cooling.

Conclusion:

That is how heat pipes, in conjunction with the whole CPU cooling mechanism, function. These heat pipes are still used in modern systems because they are so successful at their design.

They are also considered a viable alternative to liquid cooling and fan cooling systems in certain circumstances. But, the recommendation is that you consider all possible cooling methods before settling on a heat pipe-based system. Read more guides at finest desktop regarding PC build.
